Description
Mehrwegbehälter aus Stahl, insbesondere rostfreiem Stahl, für, vorzugsweise kohlensäurehältige, Flüssigkeiten, z.B. Getränke.Reusable containers made of steel, especially stainless steel, for, preferably carbonated, liquids, e.g. Beverages.
Die Mehrwegbehälter aus Stahl, welche in der Lebensmittelindustrie zum Einsatz kommen, unterliegen einer besonders starken und breiten Beanspruchung. Eine wesentliche Voraussetzung für derartige Behälter ist die Verwendung einer Legierung, welche den korrosiven Beanspruchungen durch die Lebensmittel gewachsen ist. Hiebei muß berücksichtigt werden, daß die Aufnahme von auch nur geringen Mengen an Metallen zu einer geschmacklichen Beeinträchtigung führen kann, sodaß verschiedene Legierungen, z.B. Leichtmetallegierungen, einen nur sehr begrenzten Einsatzbereich aufweisen. Weiters ist die bei Behältern aus Leichtmetallen bestehende Gefahr des Verbeulens sehr groß, wobei derartige Beulen Vertiefungen, Kerben, Linschnitte, Rillen u.dgl. bedingen, welche ausgesprochen schwer zu reinigen sind. Aus diesem Grund hat sich Stahl, insbesondere korrosionsfester, rostfreier Stahl, für den Einsatz in der Lebensmittelindustrie besonders bewährt.The reusable containers made of steel, which are used in the food industry, are subject to particularly heavy and wide loads. An essential prerequisite for such containers is the use of an alloy which can withstand the corrosive stresses caused by the food. It must be taken into account here that the absorption of even small amounts of metals can lead to a taste impairment, so that different alloys, e.g. Light metal alloys have only a very limited area of application. Furthermore, the risk of denting in containers made of light metals is very great, such bumps being depressions, notches, cuts, grooves and the like. condition which are extremely difficult to clean. For this reason, steel, especially corrosion-resistant, stainless steel, has proven particularly useful for use in the food industry.
Aus der AT-PS 319.136 wird ein Bierfaß bekannt, das aus zwei Hohlschalen gebildet ist, die durch Verschweißen miteinander verbunden sind. Beide Hohlschalen weisen an ihren einander gegenüberliegenden Enden Stand- bzw. Tragringe auf, die im Übergangsbereich zwischen dem zylindrischen Bereich und dem Boden mit den Hohlschalen verbunden sind. Eine derartige Konstruktion hat sich hervorragend bewährt. Dieses Faß weist, wie bekannt, Hohlsicken auf, wodurch die Stabilität erhöht wird und andererseits ein Rollen der Fässer besonders leicht ermöglicht ist. Beim Hantieren dieser Fässer, die im gefüllten Zustand ein relativ hohes Gewicht, z.B. 60 kg, aufweisen, ist die Gefahr, daß derartige Fässer mit Schwung gegeneinander bewegt werden, relativ gering. Damit werden diese Fässer, wenn sie gegeneinander geschlagen werden, auch nur geringfügig in ihrer Kontur, durch Dellen u.dgl., verändert. Ist es aber so, daß derartige Behälter für geringere Volumina bestimmt sind und das Breitenzu Höhenverhältnis wesentlich geändert wird, sodaß ein höherer Behälter entsteht, so kommt es zu Dellen, Einschlägen u.dgl. im Bereich, der sich oberhalb bzw. unterhalb der Stand- bzw. Tragringe befindet. Diese Dellen bewirken jedoch, daß im Behälterinneren Infektionskeime zurückbleiben können, wodurch die Haltbarkeit der flüssigen Lebensmittel im Behälter beeinträchtigt werden kann.From AT-PS 319.136 a beer keg is known which is formed from two hollow shells which are connected to one another by welding. Both hollow shells have at their opposite ends stand or support rings which are connected to the hollow shells in the transition area between the cylindrical area and the bottom. Such a construction has proven itself extremely well. As is known, this barrel has hollow beads, which increases the stability and, on the other hand, allows the barrels to roll particularly easily. When handling these drums, which have a relatively high weight, eg 60 kg, when filled, there is a risk that such drums are moved against each other with momentum, relatively small. Thus, these barrels are only slightly changed in their contours, by dents and the like, when they are struck against one another. But if it is the case that such containers are intended for smaller volumes and the width to height ratio is changed significantly, so that a higher container is formed, there are dents, impacts and the like. in the area that is above or below the stand or support rings. However, these dents cause infection germs to remain inside the container, which can affect the shelf life of the liquid food in the container.
Aus der GB-PS 1,269.626 wird ein stapelbares Bierfaß bekannt, das aus zwei zylindrischen Schüssen besteht, die miteinander verschweißt sind, welche jeweils eine Rollsicke aufweisen und deren Ende jeweils eingerollt ist, wodurch eir, Stand- bzw. Tragring gebildet wird. Der Tragring ist nach Innen versetzt, sodaß derartige Behälter übereinander gestapelt werden können, und zwar in der Form, daß ein Standring eines Fasses über den Tragring eines anderen Fasses hinweggreift. Der obere und der untere Boden wird durch Einschweißen entsprechender Formstücke in die Schüsse gebildet, wobei zwischen Schuß und Boden Spalten entstehen können, die Infektionsherde bilden. Ein derartiges Faß ist weder so ausgebildet, daß es beim Transport nur geringer Beanspruchung durch Dellen o.dgl. ausgesetzt ist noch ist das Innere frei von Spalten, Nischen u.dgl., sodaß eine extrem hohe Infektionsgefahr bei diesem Faß besteht.From GB-PS 1,269,626 a stackable beer keg is known, which consists of two cylindrical sections that are welded together, each having a rolling bead and the end of which is rolled up, whereby eir, stand or support ring is formed. The support ring is offset inwards, so that such containers can be stacked one on top of the other, in the form that a stand ring of a barrel extends over the support ring of another barrel. The upper and lower floors are formed by welding corresponding shaped pieces into the wefts, whereby gaps can form between the wefts and the floor which form foci of infection. Such a barrel is neither designed so that it or the like during transport only slight stress from dents. the interior is still exposed to gaps, niches and the like, so that there is an extremely high risk of infection with this barrel.
Aus der GB-PS 1,016.735 wird ein Bierfaß aus Aluminium oder Stahl bekannt, welches an seinem oberen bzw. unteren Ende einen in Guß gefertigten Stand- bzw. Tragring aufweist. Die beiden Böden sind über einen balligen Bereich mit dem mittleren Teil des Fasses verbunden, welcher zwei entweder in das Faß eingeformte Rollsicken bzw. angeformte Reifen aufweist. Durch diese Rollsicken wird entweder die Infektionsgefahr erhöht, und zwar insbeso dere dann, wenn diese zweckgemäß verwendet werden, da es zu kleinen Einkerbungen o.dgl. zwangsläufig kommt, wodurch im Inneren schwer zu reinigende Bereiche entstehen, bzw. bewirken angeformte Rollsicken ein erschwertes Manipulieren, wodurch erneut ein Gegeneinanderschlagen der Behälter verursacht wird, sodaß diese erneut im Gebrauch Dellen erhalten, wobei die Stand- bzw. Tragringe aus Guß, da diese eine höhere Festigkeit als der Behälter als solcher aufweist, erneut eine größere Deformationsgefahr darstellen.From GB-PS 1,016,735 a beer keg made of aluminum or steel is known, which has a cast or cast ring at its upper or lower end. The two bottoms are connected via a spherical area to the central part of the barrel, which has two roll beads or molded tires either molded into the barrel points. These rolling beads either increase the risk of infection, especially when they are used appropriately, since there are small notches or the like. inevitably comes, which creates difficult-to-clean areas on the inside, or formed molded beads make it difficult to manipulate, which again causes the containers to collide, so that they receive dents again in use, with the stand or support rings made of cast iron, since these has a higher strength than the container as such, again represent a greater risk of deformation.
Die vorliegende Erfindung hat sich zur Aufgabe gestellt, einen Mehrwegbehälter zu schaffen, der besonders leicht zu reinigen bzw. zu sterilisieren ist, selbst wenn der Behälter bereits längere Zeit in Einsatz war, welcher einen besonders geringen Platzbedarf aufweist und der so ausgebildet ist, daß bei der Manipulation der Behälter diese nicht einander, gleichgültig leer oder gefüllt, verbeulen.The present invention has for its object to provide a reusable container that is particularly easy to clean or sterilize, even if the container has been in use for a long time, which has a particularly small footprint and is designed so that at the manipulation of the containers does not dent them, indifferently empty or filled.
Der erfindungsgemäße Mehrwegbehälter aus Stahl, insbesondere rostfreiem Stahl, für, vorzugsweise kohlensäurehältige, Flüssigkeiten, z.B. Getränke, mit einem aus zwei miteinander metallisch, z.B. durch Schweißen, verbundenen, gegebebenenfalls im wesentlichen rotationssymmetrisch ausgehildeten Hohlschalen, der an seinen gegenüberliegenden Enden jeweils einen Trag- bzw. Standring aus Stahlblech trägt, welche ebenfalls metallisch, z.B. durch Schweißen, mit jeweils einer Hohlschale verbunden sind, wobei die Hohlschalen einen zylindrischen Bereich und einen Bodenbereich aufweisen, besteht im wesentlichen darin, daß der mittlere zylindrische Bereich außen und innen durchgehend zylindrisch ist und mit dem den Boden bildenden Bereich unmittelbar über einen außen und innen im wesentlichen kegeligen oder balligen Bereich verbunden ist und der Standring im kegeligen bzw. balligen Bereich und/oder im Übergangsbereich zwischen kegeligem und balligem Bereich und dem Boden mit der Hohlschale verbunden ist.The reusable container according to the invention made of steel, in particular stainless steel, for, preferably carbonated, liquids, for example beverages, with a hollow shell which is made of two interconnected metal, for example by welding, and which may be essentially rotationally symmetrical, each of which has a carrying or Supporting ring made of sheet steel, which are also metallic, for example by welding, each connected to a hollow shell, the hollow shells having a cylindrical region and a bottom region, consists essentially in that the central cylindrical region is continuously cylindrical on the outside and inside and with the area forming the base is connected directly via an outside and inside essentially conical or crowned area and the base ring in the tapered or crowned area and / or in the transition area between conical and spherical area and the bottom is connected to the hollow shell.
Bei einer derartigen Konstruktion ist einerseits sichergestellt, daß ein Behälter geschaffen werden kann, der lediglich eine Rundnaht aufweisen muß, wobei gleichzeitig durch den balligen bzw. kegeligen Bereich eine Stoßfläche mit hoher innerer Festigkeit gebildet und eine weitere Versteifung durch den Stand- bzw. Tragring gegeben ist. Weiters ist das Leervolumen und das Leergewicht bezogen auf die zu transportierende Flüssigkeit gering gehalten.With such a construction it is ensured on the one hand that a container can be created which only has to have a circular seam, at the same time a butt surface with high internal strength is formed by the spherical or conical area and a further stiffening is provided by the stand or support ring is. Furthermore, the empty volume and the empty weight based on the liquid to be transported are kept low.
Gemäß einem weiteren Merkmal der Erfindung ist der Tragring in gleicher axialer und radialer Entfernung mit einer Hohlschale verbunden wie der Standring. Durch diese Ausbildung kann beim gemeinsamen Anordnen der Behälter auf einem Transportwagen eine gegenseitige Beschädigung der Fässer besonders gering gehalten werden.According to a further feature of the invention, the support ring is connected to a hollow shell at the same axial and radial distance as the base ring. This configuration allows mutual damage to the barrels to be kept particularly low when the containers are arranged together on a transport trolley.
Weist der Standring eine rotationssymmetrische, bezogen auf die Längsachse des Behälters, ausgebildete Stufe auf, deren Innendurchmesser dem Innendurchmesser des axialen Endbereiches des Tragringes entspricht, so ist eine besonders einfache und saubere Lösung zum Stapeln der Behälter geschaffen, wobei durch die spezifische Anordnung der Trag- und Standringe eine besonders hohe Stapelbarkeit gegeben ist.If the base ring has a rotationally symmetrical step with respect to the longitudinal axis of the container, the inside diameter of which corresponds to the inside diameter of the axial end region of the support ring, a particularly simple and clean solution is created for stacking the containers, the specific arrangement of the support and standing rings are particularly stackable.
Weist die den unteren Bodenbereich aufweisende Hohlschale eine axiale kreisförmige Vertiefung auf, die im wesentlichen der Fläche der im oberen Bereich angeordneten Entnahme- und Füllöffnungsfläche entspricht, so können identisc :e Hohlschalen verwendet werden, wobei gleichzeitig durch diese Vertiefung ein Sumpf ausgebildet ist, der die Entnahme der Flüssigkeit besonders vorteilhaft erlaubt, da eine fast vollständige Entleerung möglich wird.If the hollow shell having the lower base area has an axial circular depression which essentially corresponds to the area of the removal and filling opening area arranged in the upper area, then identical hollow shells can be used, a sump which is formed through this depression at the same time Extraction of the liquid is particularly advantageously permitted, since an almost complete emptying is possible.
Sind die Stand- und/oder Tragringe an den mit den Hohlschalen zu verbindenden Bereichen zum Behälterinneren weisend abgewinkelt ausgebildet, so kann einerseits eine besonders gute Verbindung derselben mit den Hohlschalen erfolgen, wobei gleichzeitig eine gewisse federnde Kraftaufnahme durch die Ringe, bei Beanspruchung derselben, erfolgt.If the stand and / or support rings are angled at the areas to be connected with the hollow shells to the inside of the container, then a particularly good connection of the same to the hollow shells can take place, while at the same time a certain resilient force is absorbed by the rings when they are stressed .
Die Verdellungsgefahr wird dann besonders gering gehalten, wenn der kegelige bzw. ballige Bereich in den zylindrischen Bereich mit einem größeren Radius übergeht als dieser Bereich in den Bodenbereich übergeht.The risk of indentation is kept particularly low if the conical or spherical area merges into the cylindrical area with a larger radius than this area merges into the bottom area.
Im folgenden wird die Erfindung an Hand der Zeichnung näher erläutert.The invention is explained in more detail below with reference to the drawing.
Das in der einzigen Figur dargestellte Faß weist zwei Hohlschalen 1, 2 auf, die über eine Schweißnaht 3 miteinander verbunden sind. Diese Verbindung kann durch Reibschweißen, Plasmaschweißen aber auch durch eine direkte Rollnaht od.dgl. erfolgen. Die Hohlschalen weisen jeweils einen zylindrischen Bereich 4 auf, der über eine Abrundung 5 mit einem Radius R1 in einen kegeligen Bereich 6 übergeht, der seinerseits über eine Abrundung 7, welche einen Radius R2 aufweist, der kleiner als der Radius R1 ist, in einen Bodenbereich 8 übergeht, welcher, wie an sich bekannt, als Teilkugel ausgebildet ist. Der Bereich 6 kann auch leicht ballig sein. Der Tragring 9 ist, wie insbesondere der nicht geschnitten dar gestellten Hälfte der Zeichnung zu entnehmen, über eine Schweißnaht 10 mit der oberen Hohlschale verbunden. Der Tragring weist halbkreisförmige Ausnehmungen 11 auf, die insbesondere bei Waschvorgängen von Bedeutung sind, da dort das Waschwasser zum Abfließen kommen kann. Die Verbindung des Tragringes 9 bzw. Standringes 12 mit der Schale erfolgt Im kegeligen Bereich 6 bzw. Im Übergangsbereich 7. Wie besonders deutlich der linken Hälfte der Zeichnung zu entnehmen, besitzt der untere Bodenbereich 8 eine kreisförmige Vertiefung 13, die im wesentlichen der Fläche der im oberen Bereich angeordneten Entnahme- und Füllfläche 14 entspricht. Der Standring 12 weist eine Stufe 15 auf, deren Innendurchmesser dem Innendurchmesser des axialen Endbereiches des Tragringes entspricht. Der umgebördelte Rand 16 des Tragringes kann somit in die Stufe 15 des Standringes eingreifen.The barrel shown in the single figure has two
Die Trag- und Standringe weisen einen abgewinkelten Endbereich 17 auf, welcher zur Verbindung mit den Hohlschalen dient.The support and standing rings have an
